Comparing orange and pomegranate face masks
at first |
1x3 =
3 u |
5x3 =
15 u |
6x3 =
18 u |
Before |
3 u |
3x5 =
15 u |
|
Change |
- 1 u |
- 1x5 =
- 5 u |
|
After |
2 u |
2x5 =
10 u |

The number of pomegranate face masks at first is repeated. Make the number of pomegranate face masks the same. LCM of 5 and 3 is 15.
Total number of face masks in the end
= 2 u + 10 u
= 12 u
12 u = 108
1 u = 108 ÷ 12 = 9
Number of pomegranate masks at first
= 15 u
= 15 x 9
= 135
Answer(s): 135
